, Quiz: When viewed from the Earth which of these objects could appear
in a crescent phase?
Ans: Venus, a comet that crosses the Earth's orbit, small asteroid on orbit
entirely between Venus' and Earth's orbits
Quiz: Consider two planets, A and B, orbiting a distant star. Planet B
orbits twice as far from the star as Planet A does. how does planet B's
orbital period compare to planet A's?
Ans: More than twice as long
Quiz: The Asteroid Belt is a ring of debris which resides between the
orbits of Mars and Jupiter in the Solar System. If an object in the Asteroid
belt is location 2.8AU from the Sun, how long does it take to make one
complete orbit around the Sun?
Ans: 4.7 years
Quiz: Comets orbit the Sun on highly eccentric orbits (e>0.8). When a
comet is at closest approach to the Sun, it is said to be at perihelion.
When it is farthest from the Sun the comet is said to be at aphelion.
Which of the following statements is correct?
Ans: The comet is moving slower at aphelion than perihelion
